The Zope Object Database provides an object-oriented database for
Python that provides a high-degree of transparency. Applications can
take advantage of object database features with few, if any, changes
to application logic. ZODB includes features such as a pluggable storage
interface, rich transaction support, and undo.

The .tgz file is the source tarball. You must have a C compiler to build the software from this file. The .exe files are pre-built Windows installers - you need to get the one specific to the major.minor version of Python you use on Windows.

ZODB3 3.4 requires Python 2.3.4 or later.
<ul>
<li>ZODB 3.4.2 is the current stable version. It corresponds to the ZODB in Zope 2.8.2, and was released 12 October 2005.
<li>ZODB 3.4.1 corresponds to the ZODB in Zope 2.8.1.
<li>ZODB 3.4.0 corresponds to the ZODB in Zope 2.8.
</ul>
<p>
Zope 2.8 and current Zope 3 development are using ZODB 3.4. ZODB 3.4 cannot be used with Zope 2.7 or earlier.
<p>ZODB 3.4's ZEO protocol is compatible, in both directions, with ZODB 3.3's ZEO protocol. There is weak support for running 3.4 ZEO servers with pre-3.3 ZEO clients; see the <a href="README.html">README</a> file for details.

If you can read this text, it means you are not experiencing the Plone design at its best.
Plone makes heavy use of CSS, which means it is accessible to any internet browser,
but the design needs a
standards-compliant browser to look like we intended it.
Just so you know ;)
